The 2R470TK-8 Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection component designed for medium-to-high voltage applications requiring precise and reliable overvoltage protection. Built with advanced ceramic gas discharge technology, this DIP series device delivers fast response to lightning strikes, switching transients, and high-energy surge events.
With a nominal static breakdown voltage of approximately 470V, the 2R470TK-8 offers an elevated protection threshold compared to lower voltage GDTs, reducing nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, effectively protecting sensitive electronic circuits from transient damage.
The device features stable ignition characteristics, including consistent first ignition values after prolonged inactivity and reliable following ignition performance during continuous operation. It supports high switching durability of up to 2×10⁵ operations at +25°C and maintains stable performance at switching frequencies up to 200 Hz, ensuring long-term reliability under repetitive surge conditions.
Engineered for robust surge handling, the GDT demonstrates strong discharge capability under defined test circuit parameters, making it suitable for demanding environments. Encased in a durable DIP package, the 2R470TK-8 allows easy through-hole mounting and secure integration into various circuit designs.
